A turbomachine inlet transition section (110) comprising: a substantially circular entry (102); a reshaping portion (112) beginning at the substantially circular entry (102) and ending at an intermediate region (120) having a first substantially polygonal cross section, a cross section of the reshaping portion (112) changing from substantially circular at the entry (102) to the first substantially polygonal cross section at the intermediate region (120) while maintaining substantially constant cross sectional area throughout the reshaping portion (112); and a prismoidal portion (114) beginning at the intermediate region (120) and ending at an inlet transition section exit (126) having a second substantially polygonal cross section, a cross section of the prismoidal portion (114) changing from the first substantially polygonal cross section to the second substantially polygonal cross section, the first and second substantially polygonal cross sections being of the same type of polygon while being of substantially different dimension.
